Relevance. Analysis of the present range of pesticides that are used in flower orangeries showed critical shortage of allowed pesticides. Now there are no methods for registration testing of insecticides designed to protect flowers in greenhouses. Thus, the purpose of our research is to develop methodological approaches to assessment of abundance of major pests for flower cultures of protected ground and determination of biological effectiveness of new insectoacaricides.Methods. The following phytophages represent flower pests that are predominant in the protected ground: aphids: green peach – Myzus persicae Sulz., melon and cotton – Aphis gossypii Glov., greenhouse-potato – Aulacorthum solani Kalt., potato – Macrosiphum euphorbiae Thom., green rose – Macrosiphum rosae Linn.; whiteflies: greenhouse whitefly – Trialeurodes vaporariorum Wstw., silverleaf whitefly – Bemisia tabaci Genn.; thrips: tobacco – Thrips tabaci Lind., rose – Th. fuscipennis Hal., western flower – Frankliniella occidentalis Perg., heterophagous – F. intonsa Tryb., greenhouse – Heliothrips haemorrhoidalis Bouche; mites: red spider – Tetranychus urticae Koch.; red greenhouse – T. cinnabarinus BoisdResults. Researches related to assessment of abundance of major pests for flower cultures and choosing methods related to determination of biological effectiveness of insectoacaricides were performed in flower orangeries of Leningrad Region on hybrid tea roses Rosa L., chrysnatemums Chrysanthemum L., gerberas Gerbera G. As a result, the algorithm for performing tests related to study of new insectoacaricides on flower cultures in greenhouses is developed. Methodology instructions that we offer for assessment of abundance of major pests for flower cultures of protected ground and determination of biological effectiveness of new insectoacaricides are intended for ensuring the uniform methodological approach to performance of registration tests of modern means to fight against these pests and opportunity for analysis of tests in various agroclimatic areas and obtaining a reasonable general conclusion and findings related to pesticides taking into account international requirements.
